2 Abstract High rates of substance use and its associated problems afflict Cape Town, underscoring the need for easily accessible substance abuse treatment. Despite the substantial benefits for both individuals and society at large that substance abuse treatment confers, substance abusers often first have to negotiate considerable challenges in order to access treatment and accumulate these gains. That is, experiencing barriers to accessing treatment, together with the presence of socio-demographic features, rather than need for treatment, decides who accesses treatment. Referrals are the gateway to inpatient substance abuse treatment in the Western Cape. While several barriers to accessing treatment have been identified by prior studies, none examine these phenomena from the point of view of the agents responsible for referring substance users for treatment. Moreover, access barriers to inpatient substance abuse services are a neglected area in extant literature. To address this gap, this study explored the perceptions of referring agents of the barriers to accessing state-funded inpatient substance abuse treatment centres in the Western Cape. This enabled the researcher to compare existing access barriers to treatment as identified by prior research, to those elucidated in the study. Bronfenbrenner s Process-Person-Context-Time model was employed as the basis for understanding identified barriers. In accordance with the exploratory qualitative methodological framework of the study, six semi-structured individual in-depth interviews were conducted with referring agents of differing professional titles who were purposefully selected and expressed a willingness to participate in the study. Interviews were audio-recorded, and transcripts were analysed and interpreted by means of Thematic Analysis. Two broad thematic categories of access barriers were identified: Person-related barriers (denial, motivation for treatment, gender considerations, disability, active TB disease, homelessness, psychiatric co-morbidity) and Context-related barriers to treatment (cultural and linguistic barriers, stigma, community beliefs about addiction and treatment, awareness of substance abuse treatment, affordability/ financial barriers, geographic locations of treatment facilities, waiting time, lack of collaboration within the treatment system, beliefs of service providers, lack of facilities/ resources within the treatment system, practices at inpatient facilities, referral protocol and uninformed staff). Results suggest that by targeting the aforementioned barriers, access to inpatient and outpatient treatment services can be improved, and recommendations for interventions are offered in this regard. Ethical principles such as obtaining informed consent and ensuring confidentiality were abided by throughout the study and thereafter. ii

8 Chapter One: Introduction 1.1. Background to the study This study explored the barriers to entering inpatient substance abuse treatment, as identified by referring agents in the Western Cape. Given that substance use disorders are the second leading category of lifetime disorders (13, 3%) in South Africa (Herman et al., 2009), substance abuse treatment services are vital (Harker Burnhams, Dada & Myers, 2012). Though alcohol continues to be the primary substance of abuse (van Heerden et al., 2009), the use and trade of amphetamine-type stimulants, heroin and cocaine have noticeably increased in the country (Parry & Pithey, 2006). In South Africa s Western Cape Province, substance-related problems are especially pervasive (Harker Burnhams, Myers, Fakier, Parry & Carelse, 2011; Myers, Pasche & Adam, 2010b; Plüddemann, Myers, & Parry, 2008), chiefly in Cape Town its capital (Myers, Louw & Fakier, 2007). Great indirect and direct health, social and economic costs are incurred by the use and abuse of substances within the Metro region. Costs related to drugs and alcohol are mirrored in infrastructural damage, legal, medical and emergency services (Parry, 2009 as cited in City of Cape Town Policy Position on Alcohol and Drugs and Alcohol and Other Drug Harm Minimization and Mitigation Strategy, ), broader indirect effects, court cases, imprisonment, and policing (City of Cape Town Policy Position on Alcohol and Drugs and Alcohol and Other Drug Harm Minimization and Mitigation Strategy, ). This underscores the need for accessible substance abuse treatment services (Myers, Louw & Pasche, 2011; Plüddemann et al., 2008). Treatment denotes the provision of one or more structured interventions designed to manage health and other problems as a consequence of drug abuse and to improve or maximize personal and social functioning (United Nations Office on Drugs and Crime, UNODC, 2003, p. 11.2). The treatment of substance abuse confers significant societal and personal benefits (Carr et al., 2008; Fakier & Myers, 2008), and has been shown to combat several substance-related problems (Carr et al., 2008). 1

9 Monetary, quality-of-life and social gains are reported at a societal level (Ettner et al., 2006; Koenig et al., 2005 as cited in Carr et al., 2008; McCollister & French, 2003; Zarkin, Dunlap, Hicks, & Mamo, 2005) while psychiatric symptoms, substance use and criminal activity have been found to be reduced as result of treatment, at the level of the individual (cited in Carr et al., 2008). As such, prior studies allude to optimistic outcomes as a result of treatment: enhanced psychological and physical well-being; lessened substance abuse; decreased unlawful activities; advances in social functioning (Fakier & Myers, 2008), reduced health care costs and overall use of health services (National Center for Health Statistics, 2009) and lessened costs of criminality (cost of incarceration, victimisation, and losses due to crime) (McCarty, 2009). Substance dependence necessitates treatment (World Drug Report, 2012), yet substances abusers must first access treatment in order to accumulate these gains, which is often a substantial challenge (Carr et al., 2008). This is evident in South Africa s Western Cape Province, where barriers to entering treatment for substance abuse have been reported. Myers and Parry (2005) found the accessibility, affordability, and availability of South African substance abuse treatment services to be of concern. Adding to this, Myers et al. (2007) posit that the utilisation of treatment services are dependent not on need-fortreatment, but on encountering barriers to treatment, in the presence of certain sociodemographic factors which have been associated with affecting treatment utilization (Myers et al., 2007, p.1). Systemic or individual characteristics or events which serve as challenges to receiving substance abuse treatment can be termed barriers (Xu et al., 2007). The current study focuses on the role of systemic and individual influences on the accessibility of inpatient substance abuse treatment. Intensity of treatment makes reference to the level at which, and amount of substance abuse treatment provided. Outpatient, inpatient/ residential care, and a combination thereof are employed in the South African context (Fakier & Myers, 2008). Specialist treatment facilities offer AOD users specialist treatment services (e.g. inpatient treatment services and detoxification) (Shand & Mattick, 2001). The current study limits its focus to these specialised substance abuse treatment facilities as they are unique in their use of a referral system (see Myers et al., 2007). Those who refer individuals to these treatment facilities have been identified under various categories by the South African Community Epidemiology Network on Drug Use 2

10 (SACENDU) Report (2012). Using data from 21 specialist treatment facilities, this report identified that referrals are usually made by: (1) Work/employers; (2) Social services/welfare; (3) Self/ family/ friends; (4) Religious body; (5) Doctor/ psychiatrist/ nurses; (6) Schools; (7) Court/correctional services; (8) other sources (e.g. radio); (9) Hospital/ clinics; (10) Unknown sources. In contrast to the previous period during which data was aggregated for the report, researchers noted a slight increase in referrals by the substance using individuals themselves, their family or their friends (self/family/friends category). While other sources remained fairly constant, a slight decline occurred in referrals made by the Social Services/ welfare sector (SACENDU, 2012). The current study directs its attention to the perceptions of referrers in the social services/ welfare sector, more specifically, those who refer to statefunded inpatient substance abuse treatment centres. Reports in the Western Cape media call to attention the arduous tasks of Social Workers, one group of referring agents within the social services/ welfare category. Social Workers have to bear the burden of substance abuse in the Cape Flats, in addition to the heavy case-loads with which they must contend (West Cape News, 2010). Myers, Louw and Fakier (2008b, p. 40) observe that in contrast to other treatment service providers, state-funded early intervention and treatment services are under pressure to improve service coverage, dispersion and availability. It is therefore necessary to examine factors impeding access to state-funded treatment facilities, particularly when considering that 24% of the 2927 patients treated across 21 specialist treatment facilities reported the state as their source of funding, making it the most common source of funding in the Cape Town region (SACENDU, 2012). Examining these factors therefore constitutes one of the objectives of the proposed study Rationale for the study While several studies have directed attention to the barriers to treatment entry (e.g. Myers & Parry, 2005; Myers, Fakier & Louw, 2009; Perron et al., 2009; Xu et al., 2007), no research has examined this subject matter exclusively amongst those directly involved in the process of enacting referrals to state-funded inpatient treatment services, namely referring agents. Given that the barriers to accessing inpatient treatment facilities remain largely unexplored within the scholarship of treatment access (Wisdom, Cavaleri, Gogel & Nacht, 2011), the 3

11 current study presents an opportunity to add to this body of knowledge. Ascertaining the barriers to treatment entry is imperative to improving the utilisation of substance abuse treatment services (e.g. Myers et al., 2007) Significance of the study Against the backdrop of this discussion, this study sought to highlight the barriers to accessing state-funded inpatient treatment from the viewpoint of referring agents. Knowledge of these barriers will permit service providers and stakeholders to incorporate the insights of these individuals in planning interventions designed to minimize barriers to accessing treatment, making service provision more efficient, assisting referring agents, enabling more individuals to enter into treatment and decreasing the burden of disease. Enabling more individuals to enter treatment will allow them to accrue the benefits of treatment, which extends beyond the substance user (see Carr et al., 2008) Research question What are the barriers faced by those who refer substance abusers for treatment? 1.5. Aim of the study To explore the perceived access barriers to inpatient substance abuse treatment facilities as identified by referring agents in the Western Cape Objectives of the study (1) To identify access barriers to substance abuse treatment, as identified by those responsible for referring individuals to inpatient treatment services. (2) To compare existing access barriers to treatment as identified by prior research both nationally and internationally, to those elucidated by participants in the current study. (3) To make recommendations for intervention strategies aimed at facilitating ease of access into inpatient treatment based on emergent themes in the data collected Definitions Substance abuse: The World Health Organisation (2000) defines substance abuse as the ongoing use of a substance, despite awareness of the serious implications of its use. 4

12 Substance dependence: Substance dependence, as specified by the DSM-IV-TR (2000), is a dysfunctional pattern of substance use which results in distress or harm and is clinically significant, transpiring at any time over the period of one year, as indicated by at least three of the following diagnostic criteria: (1) tolerance; (2) withdrawal; (3) the substance is often taken in larger amounts or over a longer period than was intended; (4) there is a persistent desire or unsuccessful efforts to cut down or control substance use; (5) a great deal of time is spent in activities necessary to obtain the substance; (6) important social, occupational, or recreational activities are given up or reduced; (7) the substance use is continued despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by the substance (p. 197 ). Perception: The means by which incoming, sensory information is made sense of and analysed (Stratton & Hayes, 1993). Treatment: Treatment can be defined in general terms as the provision of one or more structured interventions designed to manage health and other problems as a consequence of drug abuse and to improve or maximize personal and social functioning (UNODC, 2003, p.11.2). Barriers to treatment: Barriers to treatment are events or characteristics of the individual or system that restrain or serve as obstacles to receiving health care or drug treatment (cited in Xu et al., 2007, p.1-2). Process-Person-Context-Time model: A model proposed by Urie Bronfenbrenner which posits that four interrelated components (Process, Person, Context, Time) frame our world (Bronfenbrenner & Morris, 2006). Access: Access to treatment can be understood as either realised or potential. The latter denotes that resources enabling treatment access are present, while the former makes reference to actual service utilization (Andersen, 1995). Inpatient treatment: Substance abuse programmes that deliver an array of structured interventions to address substance use disorders (abstinence-oriented interventions are included here), whilst providing accommodation in a drug-free environment (National 5

13 Treatment Agency, 2006) on a 24-hour basis (The Prevention of and Treatment for Substance Abuse Bill, 2008). Substance abuse treatment centres: Substance dependent individuals are provided with rehabilitation and intensive treatment at these public or private facilities (Department of Social Development, Minimum Norms and Standards for Inpatient Treatment Centres, 2005). Referral system: A multi-agent system whose member agents are capable of giving and following referrals (Yu & Singh, 2003, p. 65). Referral agents: Persons who facilitate the referral process of clients with more severe substance abuse problems to treatment services (Myers, Harker, Fakier, Kader & Mazok, 2008a). In this study the term referring agent was preferred Conclusion This chapter contextualised the current study, providing a background. The rationale for the study, research question, aims and objectives were emphasised. Chapter Two reviews the relevant literature pertaining to the aims and objectives of the study, together with an overview of the selected theoretical framework. Key findings from the literature are then combined into a summary of the literature. The research methodology is explicated in Chapter Three, where the research design, selection of study participants, data collection method, procedure, validity, reflexivity and ethical considerations are discussed. The analysis, interpretation and discussion of study findings are offered in Chapter 4, where results are also deliberated in relation to prior scholarship. Lastly, a conclusion of the study, detailing its shortcomings and recommendations for interventions are offered in Chapter Five. 6

14 Chapter Two: Literature Review This literature review provides an overview of research relating to accessible substance abuse treatment, using a thematic approach. It discusses the burden of harm attributable to untreated substance use; the use of substances, substance abuse treatment and the potential benefits of treatment in order to illustrate the need for accessible treatment 1. Furthermore, the manner in which the substance abuse treatment system is operative in the Western Cape is explicated as this situates the integral role of referring agents and the invaluable insights they stand to offer in identifying and overcoming barriers to treatment. The theoretical framework of the study, Bronfenbrenner s Process-Person-Context-Time (PPCT) Model, is then presented as a means of understanding and locating the barriers to treatment identified by earlier research. A brief summary of the reviewed literature then follows. In order to obtain an understanding of why accessible substance abuse treatment is needed in the Western Cape, this review commences by elucidating statistics pertaining to substance abuse in South Africa and thereafter studies that illustrate the harms that result from substance abuse. Subsequently, literature relating to substance abuse treatment and its benefits are presented The need for accessible substance abuse treatment in South Africa In light of the social ills associated with the use of substances (see Wisdom et al., 2011), possible resultant dependence, and well-documented benefits of treatment of substance abuse (see Carr et al., 2008), it is imperative to ensure that more individuals are able to access treatment. Several publications from the Medical Research Council of South Africa (Myers, Louw & Pasche, 2011; Myers, Louw & Pasche, 2010a; Myers et al., 2009; Myers et al., 2008) emphasize this need and this constitutes the focus of this part of the literature review. Among South Africans, substance use disorders are widespread (Pasche & Stein, 2012). Evidence shows rates of substance usage to be comparatively high in the Cape Metro and Western Cape (City of Cape Town Policy Position on Alcohol and Drugs and Alcohol and Other Drug Harm Minimization and Mitigation Strategy, ), in spite of the dearth of comprehensive prevalence statistics (Provincial Government of the Western Cape Blueprint 1 The first part of this literature review draws on the argument made by Myers et al. (2007), concerning the burden of harm attributable to substance abuse and subsequent need for treatment. It departs from this earlier work in its use of more recent literature and more in-depth focus upon these relevant factors. 7

15 2010). Untreated substance use disorders are commonplace in the Western Cape (Myers et al., 2011). Here 15, 8 % of adults report substance use disorders, and alcohol abuse as the most prevalent lifetime disorder (11, 4%). Amongst school-going adolescents excessive alcohol (66%) and tobacco (47%) use has been reported (Medical Research Council of South Africa, MRC, 2013). Recently the SACENDU (2012) project indicated that 2733 patients were treated across 23 specialist treatment centres and programmes during the latter half of Whilst this suggests high rates of substance use, the project is only able to account for substance users who have successfully accessed the treatment system (Parry, Plüddemann & Bhana, 2009). These figures are therefore not a true representation of substance use amongst the general, untreated population. Taken together, it is evident that a considerable number of South Africans would benefit from accessible treatment services Substance use and the burden of harm The global burden of disease (Wu, 2011) and more general burden of harm to society are fuelled substantially by substance use disorders, providing one indicator of the need for treatment (Myers et al., 2007). An individual s use of substances affects not only themselves but also their family members and the functioning of society at large. The substance user s accomplishments and health is impacted upon, as is the productivity, financial security, social networks and mental health of their families. Substance users contact with the healthcare and criminal justice systems thus cause society at large to be affected (Wu, 2011). Studies that illustrate the burden of harm attributable to substance abuse are outlined below Crime The drugs-crime nexus (Monaghan, 2012) is one indicator of how society at large is impacted upon. High levels of substance abuse were reported in a qualitative study conducted amongst South African arrestees. Amongst the sample, 50 % of 2 coloured participants reported Mandrax use, whilst this was the drug of choice for 39% of Indian participants. Cocaine use was found to be especially prevalent among White arrestees (32%), and even more so amongst White females (65%). Substance use was most likely to occur in those below the age of 20 years (66%) and those with a prior history of arrests tested positive in higher volumes 1 The terms coloured and black were employed as racial categories within the apartheid era to reinforce a segregated society (along with the other racial category, namely Indian), to refer to those who were not afforded the same benefits as whites in this era. These terms are used here merely for descriptive purposes, and does not imply acknowledgement of these terms by the author. 8

16 (51%) than those who were incarcerated for the first time (29%) (Leggett, Louw & Parry, 2011). Statistics of the South African Police Service indicate that the highest rates of drugrelated crime in South Africa were reported the Western Cape Province during the 2008/2009 financial year. Of the cases examined, were accounted for in this region (Provincial Government of the Western Cape Blueprint, 2010). As one illustration, alcohol intake was involved in a vast majority (70%) of cases of domestic violence Cape Town (Peden, 2006 cited in Peltzer & Ramlagan, 2009, p. 7) Health Substance abuse has been linked to the contraction of HIV (dos Santos, Trautmann & Kools, 2011), tuberculosis (TB) (Deiss, Rodwell, & Garfein, 2009) and Foetal Alcohol Spectrum Disorders (FASD), (Freeman & Parry, 2006) respectively. This is explored in the studies below. Dos Santos, Trautmann and Kools (2011) explored substance-related transmission of HIV amongst 21 service providers and 63 substance users. Participants were relatively uninformed of the tangible risks to well-being arising from substance use. Besides no longer using substances, their imprecise ideas did not allow for tangible strategies to safe-guard themselves from HIV/ AIDS, and knowledge pertaining to substance-related HIV/AIDS transmission was also found to be poor. Besides the heightened risk of substance-related transmission of HIV, minimal educational attainment and poor living circumstances made treatment less accessible (dos Santos, Trautmann & Kools, 2011). This is paramount as avoiding further social and health harms resulting from sustained substance use is one focus of treatment (reducing the risk for HIV among injecting drug users through harm reduction measures) (Fisher et al., 2007). Globally, the highest rates of FASD are found in the Western and Northern Cape Provinces of South Africa (Graham, 2012; Chersich et al., 2011; Freeman & Parry, 2006; McKinstry, 2005). Caused by maternal alcohol consumption during pregnancy, FASD is one of the leading causes of avoidable physical and mental retardation among infants (Centers for Disease Control and Prevention, 2001 in McKinstry, 2005). Developmental difficulties, physical dysmorphology and low birthweight are often experienced by infants suffering from the syndrome (McKinstry, 2005). These negative effects for both mother and infant further highlight the importance of accessible substance abuse treatment. 9

17 Deiss et al. (2009) ascribe the high prevalence of TB among substance users to the risk behaviours they engage in, the physiological effects of substance use and environments they frequent. Internationally, HIV-associated TB epidemics have been linked to injecting drug use, and substance users experience heightened vulnerability to TB infection and disease. Substance users encounter unique barriers to treatment for TB such as limited access to care and poor adherence (Deiss et al., 2009). Substance abuse, homelessness and psychiatric illness are more consistent predictors of non-adherence to TB treatment than are demographic factors of socio-economic status, ethnicity, age, education and gender (Farmer, 2005). Practices that serve as access barriers to substance abuse treatment include necessitating testing for infectious diseases as a prerequisite for access, rendering differential treatment, or unwillingness to admit persons who are otherwise eligible. Nonetheless, treatment seekers suspected to have infectious tuberculosis may be denied access until it has been established medically if treatment is needed prior to being admitted to a substance abuse treatment program, in order to ensure the health and safety of staff and other patients (SAMHSA, 1993). Given that poor adherence or incomplete treatment place communities and infected individuals at serious risk as it leads to remaining infectious for longer periods, resistance to TB treatment, and relapse of the disease or death, the importance of controlling the illness among substance users is underscored (Volmink & Garner, 2009) Treating substance abuse Treatment addresses the harms of substance abuse (see Jackson & Shannon, 2011), and these services have become more sought after due to the high levels of substance related problems in the Western Cape (Plüddemann et al., 2008). Literature relating to the benefits of substance abuse treatment and the manner in which the treatment system is operative in the Western Cape are presented below. Substance abuse treatment is regarded as a specialty field in the behavioural sciences and medicine by the World Health Organisation (WHO) (Myers et al., 2008a). Treatment confers specialised social, medical and psychiatric services to individuals, seeking to reverse, minimise or end the adverse social and health consequences linked to substance dependence and abuse (Fisher et al., 2007). Goals of treatment are contingent upon the modality employed and these may include harm reduction or abstinence (Fisher et al., 2007; Myers et al., 2008a). In the Western Cape various treatment services are offered (Myers et al., 2008a). 10

18 The WHO (1993) endorses that the degree of severity of substance use determine the treatment intervention strategy. Thus, as use occurs on a continuum (recreational/ occasional use, misuse, abuse, dependence), so too do treatment services. On the one end of the spectrum are primary prevention activities. These aim to ensure that substance use problems and disorders do not occur. Through the provision of treatment, early identification and management of substance use disorders are encompassed under secondary prevention activities, whilst harm reduction activities, treatment and aftercare are contained within tertiary prevention activities, activities that seek to retard or cease the progression of the disorder (Fisher et al., 2007). When treatment systems ensure that recipients access the services suited to their needs, at varying levels of intensity, as required, the continuum of care is ensured (SAMHSA, 2006). The needs of individuals with substance dependence are suited to specialised treatment services which may also be indicated for those with lower levels of problem severity in the event that early interventions were unsuccessful (Fisher et al., 2007). Inpatient treatment services in South Africa vary according to treatment modalities employed; the types of populations served, duration, and the qualifications and skills of service providers. These programmes render specialised substance use disorder treatment whilst providing a 24-hour living environment for four or more individuals. This approach is more restrictive, yet intensive than that of outpatient care, and includes services at psychiatric hospitals, stand-alone residential treatment facilities and programmes based at hospitals (Fisher et al., 2007). Inpatient treatment services also stand to benefit those who have proved unsuccessful at lower levels of care, have made multiple attempts at treatment, have minimal support for treatment, have multifaceted health problems related to substance use and have co-morbid psychiatric disorders (Fisher et al., 2007). As an aid to treating substance use disorders, the use of medication is supported by research (Rieckmann, Kovas & Rutkowski, 2010). Efficient substance abuse treatment includes the prescription of medications to deal with psychiatric symptoms; medications to deal with withdrawal; substitution medication for continued periods to substitute for illicit opiates (e.g. heroin) and medications to prevent relapse to alcohol or illicit opiate use (NHS, 2006 as cited in Myers et al., 2008a). 11

19 Detoxification is an initial phase of treatment whereby acute withdrawal symptoms of dependent substance use are eased (Gossop, 2006). On its own, detoxification does not constitute treatment, and neither does it result in long-term abstinence when used alone (Lipton & Maranda, 1983 as cited in Gossop, 2006). The strength of inpatient treatment is that motivation to change and readiness for treatment can be developed during the course of treatment (Fisher et al., 2007), however, state-funded inpatient treatment facilities necessitate a referral from a suitably qualified professional Benefits of substance abuse treatment A considerable body of research shows that treating alcohol and drug disorders lead to substantial benefits (McCarty, 2009). These include the ability to acquire and retain employment, advancements in health, reductions in crime involvement, improvements in the stability of families and financial gains for communities and countries at large. Treatment is therefore regarded as an investment with high social returns. Easing the financial burden to society that arises from problems linked to drug use requires effective and accessible treatment. The costs of treatment are superseded by its benefits (National Center for Health Statistics, 2009). Ettner et al. (2006) sought to investigate the costs and monetary benefits associated with treating substance abuse. Using the Drug Abuse Treatment Cost Analysis Programme, treatment cost data was collected with a main sample of 2567 clients. Results revealed a greater than 7:1 ratio of benefits to costs, which manifested primarily as increased employment earnings and reduced costs of crime. Added to the more direct benefits of quality of life gains and improved health, a compelling argument is made for why treating substance abuse is a worthy investment. Parthasarathy et al. (2001) explored healthcare utilisation savings in their Californian study. Treated patients experienced a 26 % reduction in total medical costs, a 39 % reduction in emergency room visits and a 35% decrease in hospital stays, while Jordan et al. (2008) found a substantial decrease in tardiness, missed work, and conflict with co-workers in their intaketo-follow-up evaluation of almost 500 study participants who also underwent treatment. 12

20 Previous studies report high rates of substance abuse in the Western Cape which causes a burden of harm to be brought to bear on society. One strategy for addressing this burden of harm is for substance abusers to enter into treatment, which has consistently shown to confer various benefits. Research also consistently shows the cost of treatment to be exceeded by its economic and social benefits. Having established the need for substance abuse treatment services and its benefits, the latter half of this literature review centres upon the process of gaining access Substance abuse treatment system dynamics in South Africa Legislation governing the provision of substance abuse treatment in South Africa In South Africa, resource allocations for substance abuse services are regulated by local, provincial and national government (Fakier & Myers, 2008), with the institution of substance dependency treatment and prevention programmes being provided for by the Prevention of and Treatment for Substance Abuse Act, Act 70 of 2008, and The Prevention and Treatment of Drug Dependency Act, Act 20 of 1992 (Department of Social Development, Antisubstance abuse programme of action, ). The Department of Social Development is tasked with advancing strategies and co-ordinating community and government efforts to combat substance use through the co-ordination and development of interventions, and in consultation with the applicable stakeholders and departments (Department of Social Development, Anti-substance abuse programme of action, ). The Western Cape provincial Department of Social Development is thus responsible for overseeing and regulating treatment centres within this region. The Government resource website (www.westerncape.gov.za) list a total of 36 registered treatment centres in the Western Cape. Twelve of these centres employ an out-patient treatment modality; fifteen are identified as being privately owned, registered organisations; three are state-owned; five are subsidised in-patient treatment facilities, and the remaining treatment centres approach remains unspecified (www.westerncape.gov.za). Relative to the entire African continent, South Africa s substance abuse treatment system is debatably the most advanced (Pasche & Myers, 2012). Prior research however suggests that the demand for treatment exceeds its availability (Myers et al, 2008; Myers, Petersen, Kader & Parry, 2012). Myers et al. (2007) posit that the limited availability of treatment resources in Cape Town is 13
